Description
Technical field
This disclosure relates to a kind of catheter and method.
Background technique
Only there is provided background technical informations relevant to the disclosure for the statement of this part, it is not necessary to so constitute first skill
Art.
Currently, being clinically frequently necessary to indwelling catheter.Catheter is chiefly used in dysuria patient, and per urethra is inserted into catheter
Into bladder, urine drainage is carried out.But currently used catheter, after indwelling bladder, when bladder inanition, urethral catheterization tube head
There is the stimulation to the bladder wall in nib contacts the bladder wall, patient tolerance is poor, and foreign matter excitement is strong.Mucous membrane of urinary bladder damage is filled
Watery blood is swollen, and the trace of blood or clot often occurs in drainage of urine, blocks catheter, and then cause disease in the urological system.
It would therefore be desirable to have a kind of catheters to overcome stimulation of the catheter head tip to the bladder wall.
Summary of the invention
To solve the above-mentioned problems, existing lead can be overcome to the disclosure by proposing a kind of catheter and method, the disclosure
The problems such as urinary catheter head tip is to the stimulation of bladder.
To achieve the goals above, the disclosure adopts the following technical scheme that
A kind of catheter, including sequentially connected head, middle part and tail portion, the front end on the head are provided with drug
Mouthful, and the outer sheath on head is equipped with the sacculus that can be filled after water-filling, to wrap up head, and on the part that sacculus can not wrap up
At least two catheterizing ports are provided with, after sacculus is full, head tip can be made to sink into be wrapped up in sacculus by sacculus;
Adjacent water injection pipe, evacuating catheter and medicine-pouring pipe are accommodated in the middle part, the medicine outlet is connected to medicine-pouring pipe,
Described two catheterizing ports are communicated with evacuating catheter, and the sacculus is communicated by water outlet with water injection pipe;
The tail portion is provided with and water injection pipe, evacuating catheter and medicine-pouring pipe are respectively corresponding connects connected water-injecting cavity one by one, leads
Urinate chamber and medicine-injecting cavity.
It is limited as further, the urethral catheterization chamber has the connectivity port that can be connected with urinal.
It is limited as further, the water-injecting cavity and water-injecting cavity are provided with closure member.
It being limited as further, the accommodating chamber inner periphery of the water cavity, urethral catheterization chamber and medicine-injecting cavity in tail portion is uniformly distributed,
It is distributed in same plane in trident.
It is limited as further, the head front end is cambered surface, and there is medicine outlet in cambered surface bottom end.
Limited as further, the middle part some be provided with length scale.
It is limited as further, the sacculus arises from cambered surface bottom end, terminates in head and middle part junction, and sacculus is in
After expanded state, head tip can be made to sink among sacculus, so that the sacculus package that head tip is filled, avoids tip and wing
The contact of Guang wall, but full sacculus is contacted with the bladder wall.
It is limited as further, respectively away from cambered surface bottom end a distance, catheterizing port is ellipse at described two catheterizing port centers
It is round.
Limited as further, the water injection pipe, the distribution of evacuating catheter and medicine-pouring pipe and endpiece water-injecting cavity, urethral catheterization chamber and
Medicine-injecting cavity trifid structure is corresponding, and evacuating catheter is located at centre, and water injection pipe and medicine-pouring pipe are located at evacuating catheter two sides.
Method based on above-mentioned apparatus, after urethral catheterization tube head enters bladder, urine can through catheterizing port along evacuating catheter from urethral catheterization
Chamber outflow, may determine that whether catheter enters bladder with this, meanwhile, the scale of middle part can measure the depth that catheter is put into
Degree;
After catheter is put into, water-injecting cavity is connected syringe injection sterile water and can be covered after sacculus is full with Filled Balloon
The whole region of catheterizing port is removed on head, and only there are the channels linked up with urine in bladder at two catheterizing ports, meanwhile, head point
End sinks into full sacculus, and full sacculus replaces head tip directly to contact with the bladder wall, exports urine.
Compared with prior art, the disclosure has the beneficial effect that
After sacculus water-filling of the present invention is full, head tip sinks into full sacculus, to avoid head tip and wing
The contact of Guang wall, is changed to the contact of full sacculus with bladder, solves the problems, such as stimulation of the head tip to bladder, water-filling sacculus has
Certain buffer function can also further decrease the stimulation to bladder.Middle part indicates scale, can measure catheter inserting
Enter depth, prevents too deep excessively shallow placement catheter.Catheterizing port in Filled Balloon, can be with perforated drainage, in catheter thickness one
In the case where fixed, increase drainage aperture, better solve catheter blockage problem.
The disclosure avoids contact of the catheter head tip with bladder, avoids catheter head tip to the thorn of bladder
Swash, can precisely hold catheter placed-depth, keeps placement catheter more scientific and reasonable, the setting of catheterizing port preferably solves
Certainly catheter blockage problem, meanwhile, the length for the catheter being placed in bladder is shortened, reduces exotic to bladder environment
It influences.
